Chapter 6 Installation
• Use the ““Chapter 9 PV module/micro inverter serial number form” on page 40 to keep
track of the inverter serial numbers as they are installed in place. The removable stickers on
the inverter (near the nameplate) should be removed and stuck to the sheet to refer to later.
The sheet will be used during the installation
tion step: see ”Chapter 7 Monitoring
Setup and Installation Launch” on page 30 for details.
6.1. Enecsys micro inverters
Micro inverters are available in various models with various power capacities and DC input
MPPT voltage ranges. Consult the datasheets on Enecsys’s website for most current informa-
tion. All technical
information is subject to change without prior notice.
!
ATTENTION: Retain the Serial Number Stickers
The serial number stickers are used to correlate the position of the inverter and
its module to its location in the installation. Without installation location informa-
tion, you will not know where each of the inverters and modules are physically
located in the array, which you will need to know for the installation setup. A
grid for the stickers is provided: see “Chapter 9 PV module/micro inverter serial
number form” on page 40.
6.2. Installing and connecting the AC bus cabling
Frame-attached micro inverters use the T-cabling system. T-cabling has molded connections
that are already
and comes with a variety of connectors that sections of cable
together and terminate AC branch connections.
6.2.1. T-Cabling System Components
• The T-Cable consists of a continuous length of cable with AC Drop cable connectors spaced
at one or two meter intervals.
• T-cables must be cut to the appropriate length for a branch circuit and terminated with a
cable end cap.
• Each AC Drop Cable connects to an inverter. Unused drop cable connectors must be cov-
ered by permanent weatherproof female caps.
• Field-installable male and female connectors are available to add more cabling options.
